ELECTRICAL HEAD-CLAMPFOR RELIEVING PAIN.

SPECIFICATION forming part of Letters Patent No. 506,516, dated October 10, 1893. Application filed May 2'7, 1893. Serial No. 475,711. (No model.)

T0 all w/z/om t may concern:

Be it known that I, LIZZIE LANE, a citizen of the United States, residing at Dunellen, in the county of Middlesex and State of New Jersey, have invented a new and useful Head- Clamp for Relieving Pain, of which the following is a specification.

This invention relates to head clamps for the relief of pain; and it has for its object to provide an improved device of this character, which while specially adapted for attachment to the head to secure relief from headache and to induce sleep, at the same time may be adapted, in the relief of neuralgia, to be fastened to the shoulder or side.

To this end the main and primary object of the invention is to provide an improved pressure clamp which of itself will press sufficiently on the affected nerves to relieve the same of their sensitiveness, and thereby reduce the pain resultingfron their affectation.

With these and other objects in view which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

In the accompanying drawingsz-Figure l is a top view'of a head showing my improved clamp in position thereon. Fig. 2 is a detail in perspective of the clamp. Fig. 3 is a detail sectional view of the adjustable or slip joints between the spring band members. Fig. 4 is an enlarged detail sectional view showing the clamp at one side of one of the circular contact plates. Fig. 5 is a view similar to Fig. 4 showing the clamp ends in contact with the plates.

Referring to the accompanying drawings, A represents a sectional spring metal band of a size adapting it for use on all sizes of heads as Well as permitting the clamping of the device to the shoulder or side in cases of neuralgia. The sectional spring band A, comprises the separateadjustable members a, carrying at one end the loops B, which loosely embrace the corresponding end of the other section so that the sections can be adjusted to enlarge or diminish the size of the clamp.

The outer free ends of the spring metal band A, are clamped inposition onto the separate metallic contact plates E. The separate metallic contact plates at each extremity of the bands A,are preferably circular to iit the temples of the head, and are slightly concaved on their inner faces to make a better contact with the body. One of said plates is made of zinc and the other of silver in order to increase the efciency of the device when the electric current is applied thereto, and on their outer faces carry the insulator clamps F. The insulator clamps F, upon the outer face of each of the contact plates, comprise separate parallel strips G, of ivory, rubber or other suitable material, clamped tightly to each other and to the contact plate by means of the eye rivets H, passing through their eX- tremities and said contact plates.

In ordinary cases the ends of the sectional spring clamp are inserted between the plates E and the clamps thereon, so as to make contact With such plates, andpit has been found useful to form the clamp members of they same material as the plates to which they are attached, so that the device will be readily susceptible to the establishment of thermoelectrical induences, by reason of thej uncture of the different metals composing the clamp members and will also sustain sufcient pressure on the affected parts as to relieve the same from pain.

In certain cases it is necessary vto secure vthe appreciable effects of .the electric current in connection with the pressure created by the head clamp, and in such cases the flattened ends of the clamp members are inserted betweenthe clamp strips G, so as to be held out of contact with the metallic contact plates. The terminals I, of an electric battery are then inserted in the eye rivets H, to close a circuit with said plates, and thereby secure a direct application of the electric-ity to the parts of the body on which the clamp may be placed. v

From the foregoing, it is thought that the construction, operation and many advantages of the hereindescribed clamp will be apparent Without further description, and I will have it understood that changes in the form, proportion and the minor details of `construction as embraced within the scope of the appended claims, may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention.

IOO

Having thus described the invention, what 1s claimed, and desired to be secured by Letters Patent, is

1. In a clamp of the class described, a sec- 5 tional adjustable spring band, and metallic contact plates having clamps removably attached to the free ends of said band, substantially as set forth.

2. In a clamp of the class desc ribeda secxo tional adjustable metallic spring band comprlsing opposite members of different metals, and contact plates removably clamped ,t0 the extremities of said members and of the same metal as the members to which they are ati 5 tached, substantially as set forth.

3. In aclamp of the class described, a spring clamp, metallic contact plates having insulator clamps adapted to receive the ext-remi- LIZZIE LANE.
